基于RBAC的分布式协同环境下的访问控制策略

Distributed cooperation environment access control based on RBAC

分布式协同环境在一些部门,企业的应用越来越多。但是传统的RBAC96模型不能解决分布式协同环境下的访问控制问题。本文通过对传统的RBAC96模型的改进,在RBAC96模型的基础上添加代理机制提出了dRBAC模型。该模型能够有效地解决协同环境下的访问控制问题。

The distributed cooperation environment is applied more in many departments and enterprises. But the traditional RBAC96 model can＇t resolve the problems of access control in the distributed cooperation environment. In this paper, through improving the traditio nal RBAC96 model, we add the delegation mechanism on the basic of RBAC96 model and propose the dRBAC model. This model can efficiently resolve the problem of access control in the distributed cooperation environment.
